1、Meet Your MemoryMemory is something that cannot be seen, touched orweighed. It is thought to be abstract. It is a setof skills rather than an object. Neither is there a single standard forjudging a good orpoormemory. There are a number of different ways in which a person may have a "good" memory.Memory is generally viewed as consisting of three stages: (1) acquisition refers to learning the material; (2) storage refers to keeping the material in the blain until it is needed; and (3) retrieval (提取) refers to getting the material back out when it is needed.Memory consists of at least two different processes: short-term memory and long-term memory. Short-term memory has a limited capacity and a rapid forgetting rate. Its capacity can be increased by chunking (组成大块), orgrouping separate bits of information into larger chunks. Long-term memory has an almost unlimited capacity.One measure of memory is recall, which requires you to produce information by searching the memory forit. In aided recall, you are given cues (提示) to help you produce the information. In free-recall learning, you recall the material in any order; in serial learning, you recall it in the orcerit was presented; and in paired-associate learning, you learn pairs of words so that when the first word is given, you can recall the second word. A second measure of memory is recognition in which you do not have to produce the information from memory, but must be able to identify it when it is presented to you. In a third measure of memory, relearning, the difference between how long it took to learn the material the first time and how long it takes to learn it again indicates how much you remember. Relearning is generally a more sensitive measure of memory than is recognition because relearning shows retention (保持) while recognition does not. Recognition is generally a more sensitive measure than recall.Paragraph 4 ______.【单选题】
A.Why do we forget things?
B.How do we measure memory?
C.What are the stages memory consists of?
D.What is the difference between short-term memory and long-term memory?
E.What is memory?
F.Who may have a poormemory?
正确答案:B
答案解析:第四段没有主题句,但迅速浏览该段会发现其中的段落衔接结构,即“One measure of memory”、“A second measure of memory”以及“a third measure of memory”,由此推知,该段主要介绍的是对记忆力进行测量。B选项How do we measure memory?(如何测量记忆?)与其意思一致,故B为正确答案。
2、Seeing Red Means Danger AheadThe colorred often means danger and by paying attention, accidents can be prevented. In the future, the colorred also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports orother kinds of materials, could one day contain a color- changing material. It will turn red before a structure collapses orfalls apart.The secret behind the color- changing material is a particular type of molecule (分子). A molecule is agroupof atoms (原子) held together by chemical bonds. Molecules come in all shapes and sizes and make up everything you can see, touch orfeel. How a molecule behaves depends on what kinds of atoms it contains and how they\'re held together.When a polymer (聚合物) containing a color- changing molecule called a mechanophore (机械响应性聚合物) is about to break, it produces a color. When a polymer with mechanophore molecules becomes "injured" orweak, one of the mechanophore bonds breaks and the material turns red. "It\'s a really simple detection method," says Nancy Sottos, one of the scientists who worked on the project. Sottos and her team tested the color- changing polymers in their lab. The test _____ proved encouraging.There is a way to get rid of the red colorlight. When a bright light is shone on the mechanophore, the broken bond is fixed and the red colordisappears. Thus "self - healing" may be a problem forengineers. They need to use the color- changer in big construction projects that will be outside, under sunlight. and sunlight will make the mechanophore\'s warning system useless.Sottos and her fellow scientists still have a lot of work to do before the color- changing molecules can be used outside the lab.【单选题】
A.results
B.rules
C.tools
D.methods
正确答案:A
答案解析:本题难度不大,考查的是词义辨析。很明显,文章此处的意思是“结果”,答案是A。
3、Cell Phone Lets Your Secret OutYour cell phone holds secrets about you. Besides the names and numbers that you\'ve programmed into it, traces of your DNA linger on the device, according to a new study.DNA is genetic material that appears in every cell. Like your fingerprint, your DNA is unique to you- because you have an identical twin. Scientists today routinely analyze DNA in blood, saliva, orhair left ______ at the scene of a crime. The results often help detectives identify criminals and their victims. Your cell phone can reveal more about you than you might think.Meghan J. McFadden, a scientist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cell phone and later dropped the device. This made her wonder whether traces of DNA lingered on cell phones even when no blood was involved. So she and colleague Margaret Wallace of the City University of New York analyzed the flip open phones of 10 volunteers. They used swabs to collect invisible traces of the users from two parts of the phone: the outside, where the user holds it, and the speaker, which is placed at the user\'s ear.The scientists scrubbed the phones using a solution made mostly of alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones back foranother week. Then the researchers collected the phones and repeated the swabbing of each phone once more.The scientists discovered DNA that belonged to the phone\'s speaker on each of the phones. Better samples were collected from the outside of each phone, those swabs also picked up DNA that belonged to other people who had apparently also handled the phone. Surprisingly, DNA showed up even in swabs that were taken immediately after the phones were scrubbed. That suggests that washing won\'t remove all traces of evidence from a criminal\'s device. So cell phones can now be added to the list of clues that can clinch a crime scene investigation.【单选题】

6、Arctic MeltEarth\'s North and South Poles are famous forbeing cold and icy. Last year, however, the amount of ice in the Arctic Ocean (北冰群) fell to a record low.Normally, ice builds in Arctic waters around the North Pole each winter and shrinks(缩小) during the summer. But formany years, the amount of ice left by the end of summer has been declining.Since 1979, each decade has seen an 11.4 percent drepin end of summer ice cover. Between 1981 and 2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner.Last summer, Arctic sea ice reached its thinnest levels. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That\'s 38 percent less area than the average cover at that time of year. and it\'s a very large 23 percent below the previous record low, which was setjust 2 years ago. This continuing trend has made scientists concerned to.There may be several reasons forthe ice melt, says Jinlun Zhang, an oceanographer (海洋学家)at the University of Washington in Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice and open water.Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water and the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.57 Celsius warmer than the average and 1.5c warmer than the previous record.With both air and water getting warmer, the ice is melting from both above and below. In some parts of the Beaufort Sea, north of Alaska and western Canada, ice that measured 3.3 meters thick at the beginning of the summer was measured just 50 cm by season\'s endThe new measurements suggest that melting is far more severe than the thinking of scientists. Some scientists fear that the Arctic is stuck in a warming trend.The word "builds" in paragraph 2 could be best replaced by ______【单选题】
A.establishes
B.expands
C.creates
D.constructs
正确答案:B
答案解析:本题难度不大,文章此处build的引申意义指“(冰层)加厚”,选项中expands是其近义解释,答案是B。
7、Don\'t Rely on Plankton to Save the PlanetEncouraging plankton growth in the ocean has been touted by some as a promising way to remove carbon dioxide from the atmosphere. Its opponents fear that will damage the marine ecosystem, and now a computer model shows that the trick would also be remarkably inefficient.Adding iron to patched of ocean can make plankton bloom temporarily. The microscopic organisms suck up dissolved carbon dioxide from the water, which in turn is replaced by carbon dioxide from the air. ______Jorge Sarmiento from Princeton and his colleagues developed a complex computer model to analyze how factors such as ocean chemistry and water circulation would affect the process if 160,000 square kilometers of ocean were seeded with iron fora month. They found that 100 years later only between 2 and 13 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.In their scenario, which covers an area 10 times as big as the largest experiment of this kind ever proposed, fertilizing the ocean removes 1 million tons of carbon from the atmosphere just 0.2 percent of the carbon dioxide humankind spews out each month. Rough estimates in the past have predicted similarly disappointing results."These are newer and better models," says Sallie Chisholm, an environmental engineer from the Massachusetts Institute of Technology."Butthe take-home message is the same. Ocean fertilization is not the answer to global warming."【单选题】
A.Its opponents argue, however, that it will stop global warming.
B.Its opponents fear that will damage the marine ecosystem, and now a computer model shows that the trick would also be remarkably inefficient.
C.As plankton die and settle on the ocean floor, their carbon is supposedly locked up in the seabed.
D.They found that 100 years later only between 2 and 12 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.
E."These are newer and better models,"
F.Ocean fertilization is not the answer to global warming.
正确答案:C
答案解析:空白前句句意:微小生物体在水中吸收溶解的二氧化碳,而水中被吸收的二氧化碳又会被空气中的二氧化碳所替代。
8、HalloweenHalloween is an autumn holiday that Americans celebrate every year. It means "holy evening", and it comes every October 31, the evening before All-Saints Day. It used to be thought the most wonderful night of the year. It was the night when witches and evil spirits came back on earth. People kept up many strange old customs in an effort to keep these evil things away. Farmers used to light big fires in their fields, and the farm workers and their families would walk around the fields singing old songs. Sometimes they would stop to hear the local priest offer prayers to the good spirits, and ask them to help keep the evil ones away. Great care was taken that none of the farm animals were left in the fields. They would all be locked up safely in their stables, and over each of the stable doors a few rowan leaves would be hung. Witches and evil spirits would not go anywhere near the rowan tree. In more recent times, Halloween has become a time forthe parties, when children dress up as witches and play all kinds of special games. After the games there is often a big supper with plenty of pumpkin pie, cakes and a lot of other delicious things to eat. But forthe most part the children enjoy the fun of dressing up and playing their favorite game of "Trick orTreat". They run down each street knocking on the doors crying loudly "Trick orTreat! Money oreat!", and most people have some sweets ormoney ready to give them. Those that do not can expect maybe to have a tyre flattened, ortheir windows covered in soap. orthe children may just knock on the doorand run away. Some children think of other people on Halloween. They carry boxes forUNICEF (The United Nations International Children\'s Emergency Fund). They ask formoney to help poorchildren all around the world. Of course, every time they help UNICEF, they usually receive a treat forthemselves, too. Every autumn, when the vegetables are ready to eat, children pick large orange pumpkins. Then they cut faces in the pumpkins and put lights inside. It looks like there is a person looking out of the pumpkin! These lights are called jack-o\'-lanterns, which means "Jack of the lantern". But in this modern age many of the pumpkins are being replaced with plastic electric ones that can be brought out each year. Which of the following statements about Halloween is FALSE, according to the text?【单选题】
A.Halloween has become a time forparties.
B.Children dress up as witches and play special games.
C.People will enjoy a big supper with many delicious things to eat
D.Children will give sweets ormoney to their parents.
正确答案:D
答案解析:第4段讲了孩子们是怎样欢喜地过这个夜晚的,敲门索要糖果吃,如果不给他们吃的,可能你的轮胎就会被放气,窗户可能会被涂上肥皂。因此选项D的内容是错误的。

10、Science Fiction1 Amongst the most popular books being written today are those that are usually classified asscience fiction. Hundreds of titles are published every year and are read by all kinds of people. Furthermore, some of the most successful films of recent years have been based on science fiction stories. 2 It is often thought that science fiction is a fairly new development in literature, but its ancestors can be found in books written hundreds of years ago. These books were often concerned with the presentation of some forms of ideal society, a theme that is still often found in modern stories. 3 Most of the classics of science fiction, however, have been written within the last hundred years. Books by writers such as Jules Verve and H. G Wells, to mention just two well known authors, have been translated into many languages. 4 Modern science fiction writers don\'t write about men from Mars orspace adventure stories. They are more interested in predicting the results of technical developments on society and the human mind; orin imagining future worlds that are a reflection of the world that we live in now. Because of this their writing has obvious political undertones (涵义). 5 In an age where science fact frequently overtakes (超过) science fiction, the writers may find it difficult to keep ahead of scientific advances. Those who are sufficiently clear-sighted to see the way we are going, however, may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology. Books written by J.Verne are____. 【单选题】
A.concerned with the problems that we will have to solve in the future
B.reading books of science fiction
C.political implication
D.a recurrent theme
E.read worldwide
F.translated into many languages
正确答案:E
答案解析:本题答案的依据是在第3段的最后一句,文章说著名科幻小说家Jules Verne的书被翻译成了多种语言,世界上许多国家的人都能读到他的书,故选E。
